The defender is entitled to any spot on the playing court she
desires, provided that she gets to that spot first, without contact
with an opponent. A defender who establishes a position directly
under the cylinder or behind the backboard when a dribbler
becomes an airborne shooter is not in a legal guarding position,
regardless if she got to the spot first. If contact occurs, the official
must decide whether the contact is incidental or a foul has
been committed by the defender. Exception: When a dribbler
takes a path to the basket parallel with the end line, the defender’s
position directly under the cylinder or behind the backboard
is a legal guarding position and, if contact occurs, the
official must decide whether the contact is incidental or a foul
has been committed by the dribbler or airborne shooter

It seems that the women's game and the NBA game are becoming more and more alike all the time, both mechanics and rule wise. As I read this, it appears to be identical to the arc rule in the NBA, just without the marking on the floor...is that correct?
